It was a good one, but it was one among many. I still enjoy the original ST, and I watched them as a teen when they first aired. I don't have a favorite but favorites, unfortunately I don't know their titles.

The first part of this "book" is a rather lengthy rant by the original author. His original story then follows. His original idea, which is nice, bears little resemblance to the episode that aired.

There are also several scripts that follow that original story - each being based on the original story, but all different from each other ... and still none that match what was aired.

From what I can gather in the authors forward there were quite a few scripts that were generated based on the original story, penned by different Star Trek principles ... from Gene Roddenberry to Gene Coon and others.
